【摘要】 目的使用根尖诱导成形术治疗成人根尖发育闭合不全伴慢性根尖周炎的前磨牙,评价其临床疗效。方法选取年龄18~26周岁,患有根尖发育闭合不全伴慢性根尖周炎的上、下颌前磨牙共18颗,使用Vitapex糊剂行根尖诱导成形术。术后分别于第2周、1个月复查,之后每3个月复查1次。复查时常规行临床检查及X线片检查。在确认患牙根尖部有硬组织形成封闭根尖孔后对其行永久根管充填。结果 18颗患牙中根尖闭合Ⅱ型者15例,Ⅲ型者3例,总有效率100%。X线片示14例根尖周低密度影像消失,4例根尖周低密度影像缩小。从根管中封入Vitapex糊剂至永久充填,平均治疗周期为10.2个月。结论根尖诱导成形术对于治疗成人根尖发育闭合不全伴慢性根尖周炎的前磨牙有良好的治疗效果。更多还原

【Abstract】 Objective To assess the clinical outcome of apexification treatment of open apices premolars with chronic apical periodontitis in adults. Methods 18 open apices premolar teeth with chronic apical periodontitis between 18 and 26 years old received apexification with Vitapex by the same operator. Patients were recalled 2 weeks,1 month,3 months after operation and every 3 months thereafter for clinical and radiographic examinations. The root canals were then filled with AH-Plus and gutta-percha when the apical barrier could be detected. Results 15 teeth formed type Ⅱ apical closure,while the other 3 teeth formed type Ⅲ. The effective rate was 100%.When observing the radiograph,we found that the healing of periapical tissue occurred in 14 teeth,while the other 4 teeth had the decrease in the size of the periapical lesions. From Vitapex sealing to permanent filling,the average time of treatment was 10.2months. Conclusions Apexification is effective to the open apices premolars with chronic apical periodontitis in adults.更多还原
